rbs and typeprof commands are unavailable by default

[JunichiIto]

What problems are you experiencing?

I installed Ruby 3.0.1 with RubyInstaller, but rbs and typeprof commands are not found in my cmd.exe. They are available by default in Mac environment which I installed with rbenv. So I had to run gem install rbs and gem install typeprof, then rbs and typeprof became available. (They appeared in C:\Ruby30-x64\bin) But they should be available by default.

Steps to reproduce

(I described above.)

What's the output from ridk version?

C:\Ruby30-x64\bin>ridk version
bash.exe: warning: could not find /tmp, please create!
